KNOW-HOW Compound …/… High-modulus carbon fibres in super-structural compounds achieve environment-friendly processes. These improvements are imposed mainly by the ever-growing precision required for parts and finished goods destined for the electrical and electronic industry, fine mechanics, the military, etc. It is evident that material specialists must find satisfactory new solutions, be it by overcoming difficulties related to intrinsic material and technology limits. Lati decided to take advantage of the dramatically higher elastic modulus of high-modulus (HM) aeronautic-grade carbon fibres to create a brand-new range of super-structural compounds that are injection mouldable. polymers, but are a perfect match for the dramatically improved mechanical performance achieved with carbon-fibre compounds. PEEK is strongly recommended for all no-compromise applications, as in the military, telecommunications and chemical industries. Lati HM – High elastic modulus compounds Creating the new breed of structural compounds required crossdisciplinary R&D collaboration across Lati’s three main divisions. Identifying the best candidate resins Since the new compounds are destined for high-end applications, only top-of-the-range base resins were taken into account for the matrix material. The polymers were selected on the basis of mechanical, chemical and thermal performance. Selecting special carbon fibres PPS: Due to its excellent chemical resistance and good mechanical performance, even at temperatures above 200°C, polyphenylene sulphide can be considered as a first step towards higher-grade thermoplastics. In particular, its exceptional dimensional stability and stiffness make PPS an excellent candidate for the practically non-deformable compounds required for precision mechanics applications. Lati opted for the high-tenacity chopped-strand carbon fibres that are traditionally used in the thermoplastic compounding industry to increase elastic modulus and load at break without introducing excessive brittleness. First, it tested the properties of high-modulus carbon fibre yarns and experimented compounding with these reinforcements. The results show that the elastic modulus of HM yarns is almost twice that of HT grades. Table 1: Behaviour of high-modulus carbon fibres.

Because PPA can provide outstanding resistance to applied loads, both static and dynamic, it is more suitable than PPA for impact-resistant applications, and the best solution for vibration-related issues. PEEK: Polyetheretherketone’s chemical, thermal and tribological properties not only make PEEK one of the best-performing Tensile modulus (MPa) Tensile strength (MPa) Thermal conductivity (W/mK) Specific heat (J/KgK) Volume resistivity (Ω/cm) 56 jec composites magazine / No50 July-August 2009
